Good value, fair quality
The ProMag brand will get you there, but it isn’t always hyper accurate with tolerances. One of the magazines had some trouble staying locked in the mag well, so I had to file down the case a little bit more below the lock ridge. This model of magazine does not use any cut out or hole to lock the magazine, it’s just a tapered cut in the magazine that makes a little shelf for the release to bite onto. All in all, they work fine. 10 rounds each, no feeding issues, good spring weight, and bolt hold open works. I would recommend these. They all have a lifetime warranty from promag so it isn’t like I couldn’t have had them swap the less functional magazine, I just didn’t want to wait that long.
